Can a fungus infecting my skin and scalp attack my brain or other organs?

After six months of being nauseous, vomiting, constant itching, covered with pustules, loosing half my hair and loosing over 50 pounds, I finally got answers: Aspergillus species (not A. Fumigatus, Flavus or Niger group) and Scopulariopsis Brevacaulis in my skin and scalp. I received the lab results yesterday, and am still waiting for the Doctor to see me. I have been having severe pain - left side -back of my head- into neck for three days. The pain is getting worse, and only seems to lessen when I apply heat to area. Could this mean that the fungus is getting worse- or attacking my brain? Please advise. Not sure how much more of this I can take. I do NOT want to go to an emergency room and sit for 6 hours- only to be told to see my regular Doctor on Monday anyway. Any advise is GREATLY appreciated. Thank You.
